Description
Technical field
The present invention relates to a kind of LED fluorescent powder composition.
Background technology
In recent years, with light emitting diode（LED）Gradually stepping up for luminous efficiency and being gradually reduced for cost, LED make
It is a kind of solid-state semiconductor material that can convert electrical energy into visible ray for a kind of new environmental type solid light source
Material, compared with other light sources, LED have energy-conservation, safety, long lifespan, energy consumption are low, generate heat less, brightness height, waterproof, shockproof, easy tune
The advantages that light, light beam are concentrated, are easy to maintenance, has become modern illumination development and the inexorable trend in future, white light LEDs are referred to as
" 21 century green light source ".
At present, gallium nitride based LED obtains white light main method and had：Blue-ray LED+yellow fluorescent powder, three-color LED synthesis are white
3 kinds of light, purple LED+three-color phosphor methods.Commercial white light LEDs are to utilize the GaN for launching 450-470 nano blue lights
Matrix LED chip and the blue light of surface coating excite the yttrium aluminate fluorescent material of the fluorescent material, mainly cerium dopping of yellow emission.This
Kind of commercial fluorescent material is there is also some shortcomings, the unstability of mainly poor color saturation and colour temperature.Color saturation compared with
Difference is due to lack red light portion in white light, and the unstability of colour temperature is due to that use for a long time moves back LED and fluorescent material performance
Caused by change.
Burst of ultraviolel white LED light source is to excite the fluorescent material of red, green, blue three primary colours assorted glimmering to produce by LED light
Light, remix what these fluorescence and LED light were realized.This white light LEDs refer to because three primary colours are various, thus with high colour developing
Number, high illumination effect, and adjustable color, and this fluorescence system is readily available, so that this mode turns into instantly
Research emphasis and focus, and be expected to turn into following white LED light source research dominant direction.
RGB fluorescent material is coordinated to prepare white light LEDs as excitaton source using ultraviolet LED, due to the fluorescent material of different substrates
Between there is radiation to reabsorb, can increase energy loss, reduce luminous efficiency, therefore the single-phase fluorescent material that ultraviolet LED excites
As mainstream development trend；Reported ultraviolet LED excites single-phase fluorescent material to have a lot, such as application number CN106929011A
The white emitting fluorescent powder that a kind of ultraviolet LED excites is provided in Chinese invention patent, its chemical general formula is M1-x-y-
